High Quality Muscovite Rigid Mica Sheet

Short Description:

R-5660-H series of Rigid Mica Plate are mica laminates designed for providing outstanding electrical insulation at high temperature, which consist of approximately 90 % muscovite (or phlogopite) and 10% high temperature resistant silicone resin.

R-5660-H series of Rigid Mica Plate are mainly used in domestic application (such as clothes irons, hair dryers, toaster, kettles, cooking appliances, microwave oven, air heater, etc.)and industrial heating applications (such as wound heater elements, cylindrical resistance heaters, metallurgy industry for intermediate frequency furnace, arc furnace, etc.).

Features

- Relative to general insulation material, the prominent advantages of the rigid mica plate are:
- Excellent insulating properties at high temperature: At 500-1000℃ operating ambient temperature, the voltage breakdown resistance is 15kV/mm;
- Excellent mechanical properties: Good flexural strength and hardness;
- Stable chemical properties: Excellent resistance to acid, alkali and oil and good aging resistance;
- Excellent environmental protection performance: The product contains no asbestos, and has less smoke and odors, even smokeless and odorless when heating;
- Excellent processability: The product can be processed into various shapes without delamination.
